Rebar End Forging
The rebar ends are cold forged to enlarge their diameter, ensuring the threaded portion maintains the barās full strength.
Thread Cutting
Parallel threads are machined on the forged ends.
Coupler Installation
The coupler is screwed onto one rebar and then connected to the second bar with matching threads.
Tightening
Both bars are tightened until a secure and rigid joint is formed.
High Structural Strength
Maintains 100% of the barās tensile strength due to cold forging and precise threading.
Material Savings
No overlapping is needed, which reduces overall rebar usage.
Fast Installation
Simplifies the splicing process and speeds up construction timelines.
Consistent Quality
Factory-machined threads ensure uniform and reliable performance.
Seismic Resistance
Provides excellent load transfer, making it suitable for earthquake-prone regions.
Versatile Application
Works with different rebar diameters and grades.
Cut the Rebar Ends
Ensure clean, square cuts for proper forging.
Cold Forge the Ends
Use a hydraulic cold forging machine to enlarge the rebar ends to the required diameter.
Thread the Ends
Cut parallel threads using a threading machine.
Attach the Coupler
Screw the coupler onto one rebar and connect it with the second bar.
Tighten and Inspect
Make sure both connections are fully tightened and aligned.
Cold forged parallel threaded couplers are widely used in:
High-rise buildings
For vertical reinforcement continuity.
Bridges and flyovers
Where high tensile strength is required.
Industrial structures
Heavy-duty projects with dense reinforcement.
Seismic zones
Areas that need robust earthquake resistance.
Precast construction
For joining bars in precast elements quickly and securely.
Strength
Couplers provide full bar strength, while lap splicing depends on overlap length and concrete bonding.
Material Efficiency
Couplers eliminate the extra steel required for overlaps.
Construction Speed
Couplers simplify installation and speed up work.
Space Savings
Reduced congestion in heavily reinforced areas.
